Detective Chief Inspector Paul Livingstone, senior investigating officer, said: "This was a violent attack on two men in the early hours of Christmas Day, which has sadly culminated in the death of a 43 year old man.

"I would like to speak to anyone who was in the vicinity of Ashgill Road at the time of the incident to come forward.

"This area is highly residential, and I am confident that there will be people who may have heard the disturbance or who may have witnessed it that we haven't yet spoken to.

I would urge these people to speak to police. A man has lost his life following a sustained attack on Christmas Day, and his family and friends have been left shattered.
